-Template repository for DHL Python packages. 
+Template for creating Python packages. 
 
-This template provides a skeleton directory structure for creating a [Python package](https://docs.python.org/3/tutorial/modules.html#packages). Python packages are collections of [Python modules](https://docs.python.org/3/tutorial/modules.html). For many projects, a single Python module is sufficient. Packages are for projects that may need to combine multiple modules.
+This template provides a skeleton directory structure for creating a [Python package](https://docs.python.org/3/tutorial/modules.html#packages). Python packages are collections of one or more [Python modules](https://docs.python.org/3/tutorial/modules.html). The package is configured in the file `setup.py`.
 
-These packages can be installed into a Python virutal environment directly from the Github source code, i.e. `pip install git+<repository URL>`
+Packages are meant to be installed into a Python environent uisng [`pip`](https://pypi.org/project/pip/). These packages can be installed directly from the GitHub source code, i.e. `pip install git+<repository URL>`
+
+Once the package is installed, the modules in the package can be imported into another Python file using [`import`](https://docs.python.org/3/reference/import.html). Modules can also be command-line applications or scripts.
